It’s pretty helpful for medical emergencies and getting through border police as a family.

I think the only correct answer will be “there are lots of different reasons”.

My wife took my last name, even though it’s not a good one and I suggested that we pick a new one.

Here are a couple of her reasons:

1. She wanted us to have the same surname.

2. She was very close friends with my cousins growing up, so the name didn’t seem weird to her.

3. Tradition - she’d always assumed she would change her name to her husband’s name, so that seemed the most normal thing to do.

Many people are fine with changing their names and the ones that aren’t won’t do it. There’s your answer. Don’t rag on the people that like changing their name.

Pew Research has survey data germane to this question. As it stands, a clear majority (79%) of opposite-sex married women changed their family/last name to their husband’s.

But for never-married women, only a third (33%) said they would change their name to their spouse’s family name. 24% of never-married women were unsure whether they would or wouldn’t change their name upon marriage.

From this data, I would conclude that while the trend of taking the husband’s last name is fairly entrenched right now, the public’s attitude are changing and we might expect the popularity of this to diminish over time. The detailed breakdown by demographic shows that the practice was less common (73%) in the 18-49 age group than in the 50+ age group (85%).

However, some caveats: the survey questions did not inquire into whether the never-married women intended on ever getting married; it simply asked “if you were to get married…”. So if marriage as a form of cohabitation becomes less popular in the future, then the change-your-family-name trend could be in sharper decline than this data would suggest.

Alternatively, the data could reflect differences between married and never-married women. Perhaps never-married women – by virtue of not being married yet – answered “would not change name” because they did not yet know what their future spouse’s name is. No option for “it depends on his name” was offered by the survey. Never-married women may also more-strongly consider the paperwork burden – USA specific – for changing one’s name.

So does this help answer your question? Eh, only somewhat. Younger age and left-leaning seem to be factors, but that’s a far cry from cause-and-effect. Given how gradual the trend is changing, it’s more likely that the practice is mostly cultural. If so, then the answer to “why is cultural practice XYZ a thing?” is always “because it is”.

I think each woman has her own reasons (some people actually like traditions) but I have the impression that, globally, women are not the same as what we see online. I think today the taking of a surname does not indicate ownership or property, at least to most modern women (and men).

I don’t think any woman thinks like that anymore, or perhaps not many, so the motivations would then also be obviously different.

Can’t speak for all women, but I (and I imagine some others) changed my name because I knew I’d be having kids and didn’t want there to be any confusion. Like, if I’m traveling internationally or if my kid ends up in the hospital, I don’t want one of us having to fish out a birth certificate to prove we’re both the parents. Also I’m of the percent that absolutely hated my long last name so the chance for my name to be shorter and nicer was a no brainer.

I’ve dated a few people who seemed progressive, and I’m a woke-ass queer, but names were a sticking point. I have a complicated welsh travesty of a name I would happily trade in for something shorter - so when I got engaged and I didn’t like his name either, and neither did he, I suggested we both pick something new and change our names together. I mean, if it’s no big deal for me to change my name, it shouldn’t be for him either, right? Anyway, I’m single now.

Yeah but it’s easy when both parents already had the same last name 🪕

She takes my hoodies, my snacks, my cash, the blankets… why wouldn’t she take my name?

(She didn’t take my name.)

My SO and have talked about possibly changing both of our last names when married. Neither of us are tied to or really care about our current names for any reason so why not just start fresh.

Well, my last name isn’t my mom’s last name, it’s my dad’s, and her last name was her dad’s, then her husband’s. So why do I care, I don’t get a matrilineal name anyway.

I hyphenated, because we both had kids when we got married, and it made it easier to deal with the school stuff for my stepkids.

Otherwise, I really just don’t care because my family name is my dad’s name and it was only my mom’s name because she changed hers to his. Not that I didn’t care about my dad, was closer to him than my mom. I just mean I don’t feel like it means anything.

ETA: as the OP says, though - I really, truly don’t understand it when a lady has a cool last name and the man an awful one and they still use his. I used to work at a payroll place and saw this happen over and over, someone would be calling up for us to change their last name from, say, Valiant or DeLeon to Assing, or Fuckler or something . Really, why wouldn’t he be the one happy to change in that scenario?

I took my husband’s last name because it was important to him, and I wasn’t super attached to mine. Also, it has 2 Z’s in it, and that’s one of the coolest letters.

I had discussed it with my wife. I didn’t want her to feel obligated to do so, and I know it would be awkward at her work to change her last name, but ultimately she wanted to - so I guess that’s one reason?

There is a degree of closeness from it that I think some people appreciate. If you all share a last name, perhaps you feel closer as a family? I’ve known some people that don’t share the same last name as their kids, or people that went double-barrelled, but didn’t with their kids, and some of them had either changed later, or regretted not having the “same” name.

My husband and I were not married when our kids were born. I wanted to have the same name as my kids So I gave them my maiden name. I never really liked that name and I wasn’t particularly close to my dad, so when my husband and I got married, we all changed our names to his.

A. Many men would not marry a woman who didn’t take their name.

B. Makes parenting more difficult in social settings by not sharing the last name of your kids. I.E. Picking up your kid at school or making medical decisions about kids and having a different last name as the child forces you to jump through a lot more hoops.

C. Women tend to grow up knowing they are going to change their last name it’s not even an afterthought. My girlfriend told me her and her friends would often talk about what their name would be if they married a guy they liked.

D. In some states it is very difficult for a man to change their last name but for women the processes is already in place.
